Andrey Zagrebin commented on FLINK-10515:
-----------------------------------------
I think the problem is that Web UI has one field for space-separated arguments.
It is historical and usually more natural for users. Therefore, we still need
the tokenisation somewhere. Then we might want to keep it on Java server side
if not in Web UI.
Alternatively, we could also somehow add a switch to the list of arguments in
Web UI as well. E.g. multiline textbox for newline-separated arguments or
adding textbox for each argument.
